Questions

What is the time difference between HST and CST?

Right now CST is 4 hours ahead of HST. The gap can change by an hour when daylight saving time starts or ends, because not every zone switches on the same date (or at all).

How do I convert HST to CST?

Add 4 hours to the HST time. For example, 12:00 PM HST is 4:00 PM CST.

Is it CST or CDT right now?

People often say “CST” all year, but during daylight saving time (mid-March to early November in the US) the zone is on CDT. It's CST right now. The converter above uses the correct one automatically.
